This battery is stated by others to be manufactured by Johnson Controls(JC) and to be an AGM constructed battery. JC is a large and reputable manufacturer and AGM technology is (one of) the preferred ones for solar and other RE applications. If the above apply and you get a good charge controller/charger with the typical more sophisticated charging algorithms of RE systems, and do not let it overheat (RE chargers usually come with a battery temperature monitor), I would think it should serve you well. Even if I does wear out faster then the more expensive RE batteries on the market, since they cost 2.5X more, you may come out ahead. Since there is a Walmart near my house, I plan to use these with the solar system I install this spring for the above reasons. Solar installers always advise not to skimp on batteries, but with the stated specs this option looks like a winner to me, especially if you are installing a grid-tied with battery backup system where the batteries will be maintained at full charge most of the time with your chargers "trickle charge" cycle, and only deep-cycled at times the grid is down. I would think these also a good choice for off-grid applications, but you should probably get at least 4 for a 24V system and 8 for a 48V system for a typical home system (all depending on the amount of backup needed and the size of your array for charging - remember the number of cycles you get will be related to the depth of discharge, & for the 24V & 48V systems above you will get around 531 and 1062 VAHrs of power over a 20hr period respectively without exceeding the batteries specs without recharging). When the sun is shining you can add your PV output to that. You also lose power from inefficiencies in charging and power factor corrections for your systems use, so kWHrs is always less than VAap (the numbers above).
How many solar panels you need depends on the energy demands of your loads, but with full direct sun 6 X 250W panels (small for a home system) would probably recharge the above use in an hour-plus, allowing for losses in conversion and power factor correction. In a day, you'd have 3 hours to spare with optimal conditions.
Hope this helps.

You would want the Deep Cycle version of this battery ( Group Size 29DC ). The wattage of your solar panel(s) just determine how long it will take to recharge a battery based on the level of discharge and total Ah rating of the battery, hours of direct and indirect sunlight available etc. As long as your panels are 12 Volt panels and receive good sunlight, they will recharge a 12V battery. However, the higher the wattage of your solar panel(s), the more quickly the battery will be recharged. Also remember that direct sunlight allows the panel(s) to produce higher power output than indirect or low sunlight conditions.
Hope this helps you out.

Good morning. I do not have any information on this and I cannot recommend you use the battery for anything other than what it is designed for. That battery,in a Marine fitment, is a deep cycle battery that is good for starting, trolling, and RV if that will help you.
